2 Claims. l

This application is a division of our application No. 467,224, ledNovember 28, 1942, which issued as U. S. Patent No. 2,345,053 on March28, 1944. Like that parent case, the object of this invention is toprovide a nut of sheet material with eiective means for holding it indefinite position on a support of wood or similar material, so that thenut may be readily attached to the support and immediately upon mountingbe available for the reception of a threaded bolt or screw withoutrequiring the application of a wrench to hold the nut.

In accomplishing the result we provide a body of sheet material with thebolt opening and embraced by a clip having bolt openings registeringwith the opening of the body and having a diverted edge about one of theclip openings to engage the thread of a bolt. The sheet metal body hasbifurcated portions bent at right angles to the body to provide twopairs of attaching legs. The legs are comparatively narrow and for themost part parallel with each other and lie in the same plane inedge-to-edge alignment being spaced apart by an intermediate notch. Thelegs are long enough and of narrow enough width so that they may be bentoutwardly in their own plane. their inner edges adjacent their free endsso that as they enter the wood or other support they will be caused toare or bend outwardly and thus obtain a rm hold on the support.

In the drawing, Fig. 1 is a side elevation of our fastening devicemounted in place in a wooden board and associated with a plate to beattached and a clamping screw; Fig. 2- is a longitudinal sectih throughthe fastening device applied to a wooden board; Fig. 3 is an end View ofthe parts shown in Fig. 2, sectioned through the board, as indicated bythe line 3-3 in Fig. 2; Fig. 4 is a perspective of the two parts of thefastening device separated; Fig. 5 is a sectional perspective of thelower arm of the fastening clip.

The body portion of our fastener is made of a single piece of springsheet metal and has an intermediate region I9 of considerable widthnarrowing toward each end. A bolt opening I2 is made in the wider partof this base in a region which is offset upwardly from the end portions.

At the ends of the base portion II, the metal is turned down at rightangles and is intermediately notched to present at each end a pair ofthin, narrow legs I5 parallel with each other and spaced apart and lyingin the same plane. These legs are beveled inwardly at their lower endsas shown at I6, which causes the legs to (Cl. {i5-32) Furthermore, theselegs are beveled on hare outwardly when driven into a piece of wood.

The thread carrying portion of the fastener is a sheet metal member 2l]doubled on itself to produce a lower arm having a bolt opening ZI and anupper arm carrying a diverted thread-engaging portion shown as a pair oftongues 22, on opposite sides of an opening 23, the tongues beingnotched at their edges at 24, and warped as in Fig. 1. The lower arm ofthe clip may have a projection 25 (Fig. 5) about the opening 2l tooccupy the hole I2 of the body and lock the clip thereto.

The upper arm of the thread engaging member is preferably curvedupwardly slightly at its free end as shown at 26. Just back of this freeend the distance between the two arms is normally less than thethickness of the intermediate region of the leg-carrying member, so thatthe clip may snugly bind on the elevated intermediate region of thebase.

In using the fastener of this invention, the thread carrying member isshoved laterally across the leg-carrying member. The open mouth of thedoubled member readily receiving the edge of the raised intermediateregion II, which cams the arms apart slightly and allows the threadcarrying member to be readily slipped across the legcarrying member. Infinal position, the fold of the thread-carrying member abuts one edge ofthe leg-carrying member, while on the other side of the latter memberthe free edges of the two arms grip it so that the doubled member isheld in place. In this position the lower arm of the doubled member liesbetween the two offset portions of the securing member and hence may notshift longitudinally.

Figs. 1 and 2 show the device of Fig. 4 in position on a wooden board Aand a bolt opening a. The two legs I5 are apart in the manner shown inFig. 3. The securing member is thus ,effectively held in position on thewooden board and holds the thread carrying member in registration withthe bolt opening a. to receive the bolt without the necessity of anywrench applied to the nut.

Our fastener may be made economically from spring sheet steel by diesand bending tools. By forming the attaching legs from a narrow portionof the fastener body so that they stand comparatively close together,the two legs may be readily driven into the wood by the blow of a hammeragainst the body portion at the end of the legs without danger ofdistorting the body. When in place the spread legs firmly attach thefastener.

We claim:

1. A combined nut and mit holder comprising a nut holder provided from astrip of sheet metal dening a -body portion having a bolt opening, anoffset portion on either side of the body portion dening spacedshoulders, attaching prongs defined by end portions of said stripprojecting in the same general direction as said offset portions, and anut carried by said body portion comprising bolt engaging meansoverlying the bolt4 open.- ing in said body portion and a nut retainingelement underlying said body portion and engaging the spaced shouldersdened by said offset portions.

2. A combined nut and nut. holder comprising a nut holder provided froma stri-p .of sheet metaldefining a body portion having a bolt opening,an offset portion on either side of the body portion defining spacedshoulders, and pairs of attach- Aing prongs defined by end portions ofsaid strip `inedrloy said offset portions.
